IMPROVEMENT vIN COKE-OVENS.

Specification forming partofV Letters Patent No. 171,371 dated December 2l 1875 application tiled November 27, 1875.

To all whom it may concern:

Be it known that I, EMIL S. GOBIET, of

Mahrisch Osterau, in the Empire ot' Austria, have invented a-certain new and Improved Coke-Oven, of which the following is a specication:

This invention is illustrated in the accompanying drawing, in which Figure l represents a longitudinal vertical section in the plane .r m, Fig. 2. Fig. 2 is a horizontal section in the plane y y, Fig. l. Fig. 3 is atransverse section in the plane z z, Fig. 2. Fig. 4 is a similar section in the plane m' x', Fig. 2.

Similar letters indicate corresponding parts.

This invention consists in combiningwith a coke-oven a series ot' side tines, bottom flues, and top tlues, the side tlues being made to communicate with the interior ot' the oven in such a manner that the heated gases which escape from the oven envelop said oven from all sides, and thereby a uniform heat is produced, and

. the formation of coke is materially facilitated.

In carrying out my invention I generally arrange the ovens in groups of ten or more, and I connect two such groups to a common chimney. In large factories I arrange two rows of these groups, so thatroom is left between them Jfor the discharging-machine, which is supplied by both rows. In each group are a series of ovens, A, which are entirelyindepend- Vent one from the other, and which have nothing'in common, except the main iiuep above, and the 1 artition\valls between, each other, so that each oven can be used separately, it desired. Each oven is provided with two supply-funnels, q, which extend down through the top, and which are provided with castiron covers lined with tire-clay, so that they can be closed immediately after the oven has been charged. Previous to introducing the coals the ovens are heated to a white heat, and as the coals pass into these heated ovens they evolve a quantity or" gas, which is immediately ignited, and passes in a burning condition all around each oven, so as to envelop the same in a complete sheet of re, and heat A it uniformly at all points. The gases which rise in one oi' the ovens escape through the lateral channels and into the upper side rines b b, which extend along one side ot' the oven,

l and which communicate through channels c c,

'b d in a zigzag course.

at their outer ends, with the lower sidelines d d. From these loweriiues the burning` gases pass through channels e e into the bottom iiues f, the channels e e being situated at vthe inner ends ot' the side lines d d, so that the burning gases must travel through the iiues The ues f are situated beneath the sole of the oven, and they extend from the center toward the outside of the walls, inciosing the ovens where said l'lues connect bychannels g with the return-tluesf, which communicate at their inner ends by scending channels e c with the lower side fines d d. From the outer ends of the-se lower side tlues the burning gases ascend through channels c' c into the upper side tlues b b', which communicate at theirinner ends through ascending channels o o with the main tlue p.

By referring `to the drawing it will be seen that the side iiues b b dd are situated on one, and the side tlues b bd d on the opposite,- side ot' each oven, so that the burning gases in passing through these tlues will heat each oven uniformly from all sides, and no additional fuel is required to keep up the required heat in the ovens. From each ofthe junctions of the ascending channels o o with the main tine p extends a Alateral flue, m, toward the outside of the brick wallv inclosing the ovens,

where the same is closed by'a suitable cover. Through these lateral lines maccess can be had to the ascending channels o o, and the circulation of the burning gases can be regulated by suitable dampers o', which, when used, will act on the channels o o, and which can be operated through the iiues m m.

In order to keep up the heat of the ovens to the required degree it is desirable to eiect the operations of charging and discharging chine which runs on a track at the side of the structure, and which is provided with a plunger fitting the ovens. This machine, however, forms the subject-matter oi' a separate application for a patent, and I will not describe it any further in this present specification. The ovens A A are provided with doors at both ends, said doors being made of' cast-iron and lined with tire-clay. These doors are raised and lowered by a block and fall, or by a windclosed as much as possible. By these means .the ovens, after they have been once heated up, can be kept going for an indefinite time without requiring any additional fue] to heat them, and if one or more of the ovens should These openings have to be keptv become defective they can be thrown out of operation and repaired without disturbing the action of the remaining ovens-in fact, each oven can be run ,independent of all the rest,

if desired.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of side ues b b d d and bottom tlues ff, the ilues a, with each other and with an oven A, substantially'as shown and described.

2. rlhe combination of a series of ovens,vA,

with side ues b b d d', bottom flues ff', ascending ues 0, the tlues a, and a common main iue, p, substantially as set forth.

3. The combination of lair-cghannels rw' with the side ues b b dgl', the uesd, Ya-nd-`yvitl1 an oven A, said channels serving to admit the requisite quantity of oxygen to support combustion, substantially as described.

In testimony that I ,claim the tloregoing I have hereunto set my hand and seal this 23d day of October, 1875.
